Ugh, it cooked my little betta :(
Well, it seemed to be working fine for a few months and then one day I found my betta dead in the tank. A quick survey of the crime scene revealed that the temperature was all the to the top of the thermometer(100plus) AND The heater was still on. Even though I’m sure that I got a defective one, maybe it was too powerful for my 3G tank in the long run anyway.
